IG-42



The Professional RF Signal Generator IG-42 came on the market in 1962 and was produced until 1979. It was the successor of the LG-1 that came on the market in 1953. There is only minor differences between the LG-1 and the IG-42. The IG-5242 replaced the IG-42 and was produced until 1980. Again there is only minor differences between the IG-42 and the IG-5242. Mostly it is a matter of different color and style. The IG-42 is heaviliy screened and is a more professional grade Signal Generator compared to the IG-102. On my IG-42 I have replaced the RF output connector to the BNC-type. Some of the knobs are not the original ones but they were replaced already when I got it.
